Was that the plan? As far as I knew Guy and John were still going to share billing on GLC, with Kyle still in New Guardians. There weren't any announcements about Guy getting a title of his own. I wouldn't be against it.
In DC's June solicitations, there is mention of Guy making a major change in GLC and then suddenly appearing in the Red Lanterns
book (the covers of both GLC and RL feature Guy, with the latter featuring him decked out in a Red Lantern uniform).
In a pre-departure interview Fialkov gave, he mentioned his plans to raise the profile of RL among the other Green Lantern titles and have it become a sister book to GLC. One sure fire way for that to have happened is if Guy had taken over the book, IMO.
That would also give all five Earth Lanterns some space to be on their own if they were divided like this:
Hal: Green Lantern
(plus Justice League
Guy: Red Lanterns
John: Green Lantern Corps
Kyle: New Guardians
Simon: Justice League of America
John has sorely needed some time in the spotlight for a long time. He's the most underused Lantern, and hasn't really had a good story in a couple decades.
Agreed. He's been thrown a bone here and there, but usually as the joyless Earth Lantern who makes the unpopular decisions.
